John_Henry,
You said:
There certainly has been speculation throughout the course of time, but no official teaching on the fate of unbaptized infants. The current catechism merely speaks of commending them to God’s mercy.
I think this may be a bit misleading without further explanation, but let me know if I’m misunderstanding Catholic teaching.
The fate of souls (infants included) who die in original sin was
officially taught at the Council of Florence:
“The souls of those who die in actual mortal sin, or only in Original Sin, immediately descend into Hell” (Denzinger 693).
Likewise, from Pope St. Zosimus:
"If anyone says that, because the Lord said ‘In My Father’s house are many mansions,’ it might be understood that in the Kingdom of Heaven there will be some middle place, or some place anywhere, where the blessed infants live who departed from this life without Baptism, without which they cannot enter into the Kingdom of Heaven which is life eternal: Let him be anathema. (Pope Zosimus at the Council of Carthage XVI)
My understanding is that the above teaching is considered a *de fide dogma *of Catholicism (infallible) (cf. Ludwig Ott,
Fundamentals of Catholic Dogma). However, what has not been definitely declared by the Church is whether infants who lack *sacramental *baptism are necessarily omitted from the possibility of *nonsacramental *baptism (by desire or by blood, for example).
So, without proclaiming a definitive dogma one way or the other, the Church merely leaves the fate of infants who have not been *sacramentally *baptised to the mercy of God (thereby, there exists the prayer and hope that they are somehow *nonsacramentally *baptized).
This hope is especially justified, given the assertion by Pope Pius IX that God does not “permit anyone to be punished eternally unless he had incurred the guilt of voluntary sin.” (Denzinger 2866). The current Catechism also assures the faithful that this hope is part of official Catholic teaching:
CCC 1261 “As regards
children who have died without Baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them. Indeed, the great mercy of God who desires that all men should be saved, and Jesus’ tenderness toward children which caused him to say: “Let the children come to me, do not hinder them,”
allow us to hope that there is a way of salvation for children who have died without Baptism. All the more urgent is the Church’s call not to prevent little children coming to Christ through the gift of holy Baptism.”
Thus, baptism (sacramental or unsacramental) is
ABSOLUTELY necessary for salvation. As I understand, infants who die without *either *sacramental or nonsacramental baptism cannot enter into heaven, according to official teachings of the Catholic Church. However, whether infants who die without sacramental baptism can be said to have been unsacramentally baptized by desire or by blood is still a speculative opinion with Catholic theology.
